Given equation is
[tex]3(x-4)=18[/tex]
Dividing both sides by 3, to eliminate 3 from the left side of the equation.
[tex]\frac{3(x-4)}{3}=\frac{18}{3}[/tex][tex]x-4=6[/tex]Adding 4 both sides to eliminate -4 from the left side of the equation, we get
[tex]x-4+4=6+4[/tex][tex]x=10[/tex]Hence the solution is x=10.
